| * |
| * Porting note: The implementation of these functions is very platform specific. |
| * Not all platforms can do real memory mapping. Those that can't |
| * still must implement these functions, getting the data into memory using |
| * whatever means are available. |
| * |
| * These functions are part of the ICU internal implementation, and |
| * are not inteded to be used directly by applications. |
